SPECQIFICATION forming part of Letters Patent N 0. 648,044, dated April24, 1900.

Application filed February 8, 1900. Serial No. 4,495. (No model.)

To all whom it may concern:

Be it known that I, THOMAS B. MILLER, a citizen of the United States ofAmerica, residing at McKeesport, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inChalk-Line Cases, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to certain new and useful improvements inchalk-line cases and is particularly adapted for use in connectionv withtape-measures or chalk-lines.

The object of my invention is to construct a chalk-line case providedwith means to permit of the chalk contained in the case coming intocontact with the tape measure or line, so that when the same is pulledfrom the case and operated in the usual manner for marking a sufficientquantity of chalk will be deposited, making a clear and distinct line.

With the above and other objects in view the invention iinallyconsistsin the novel construction, combination, and arrangement of parts to behereinafter more fully described, and specifically pointed out in theclaims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and

wherein like numerals of reference indicate corresponding partsthroughout the several views, in which- Figure 1 is a side view of myimproved chalk-line case. Fig. 2 is a vertical sectional view taken onthe line 2 2 of Fig. 1. Fig. 3 is a front view of one of theagitating-wheels forming oneside of the reel. Fig. 4. is a front view ofthe operating-pinion and revolving rack. Fig. 5 is a longitudinalsectional view of a portion of the reel, bearing-shaft, and pinion. Fig.6 is a cross-sectional view of the upper portion of the case, showingthe outer end of the tape-measure or chalk-line.

Referring to the drawings by reference-numerals, 1 and 2 indicate a pairof cylindricalshaped telescopic sections forming the case, each havingits outer face provided with a circumferential groove 3. Formedcentrally of the inner face of the section 1 is a bearingstub 4., uponwhich is mounted a hollow bearing-shaft 5, carrying on its one end arotating pinion G.

Mounted upon the bearing-shaft 5 and keyed, as at 7, to the pinion 6 ismy improved reel, which consists of a hollow sleeve or hub S, providedat each end with a pair of diametrically-opposite lugs 9 for securingthereto the agitating-wheels 10, forming the sides of the reel. Theseagitating-wheels are provided centrally with an opening 11, having apair of diametrically-arranged notches 12, to permit of the mounting andsecuring of the same upon the hub or sleeve S. Each of the Wheels isprovided with radially-arranged openings 13 to permit of the passage ofthe vchalk therethrough. The outer ends of the wheels are bent inacurvilinear manner, as at 14, which operate within the grooves 3.

The section 2 is provided at its lower end with an opening in whichrotates a bearingsleeve 15, formed integral with a disk 16, having itsinner face formed with a concentric rack 17. This rack is operated bymeans of a handle 18, suitably secured to the sleeve 15. Secured to theinner face of the section 2 is an auxiliary casing 19, provided with anopening through which projects the hub or bearing-shaft. The section 1is provided with `an offset 20 to limit the movement of the section 2when telescoping one within the other.

The operation of my improved chalk-line case is as follows: Assumingthat section 1 has been removed and a quantity of chalk placed therein,the section is replaced, and as the tape or line 2l is withdrawn throughthe nipple 22 the same willrevolve the wheel, carrying theagitating-wheels therewith, agitato the chalk, force the same intocontact with the tape measure or line, so that when the line or measureis used a sufficient quantity of chalk will be deposited to make a clearline. When it is desired to wind the tape measure or line upon the reel,Athe handle 18 is revolved, thereby-.operating the rack 17,

' causing the hub and the pinion 6 to revolve,

thereby rotating the reel and causing the tape or line to Wind thereon.It will of course be observed that 'not only does the wheel 10 agitatethe chalk by the arrangement of the openings, but prevents the chalkfrom clogging, as the same can pass through the openings at each side ofthe tape measure or line.

It is thought that the many advantages of my improved chalk-line can bereadily understood from the foregoing description taken in IOOconnection with the accompanying drawings, and it will be noted thatvarious changes may be made in the details of construction withoutdeparting from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. A chalk-line caseconsisting of two telescopic sections, abearing-stub formed integral With the inner face of one ot' saidsections, a bearing-shaft mounted on said stub, a rotatin g pinionsuitably connected to said shaft, and a reel suitably mounted on saidshaft and connected to said pinion, and means for revolving thesaid'pinion.

' ably connected to said shaft and operating Within said auxiliarycasing, a reel mounted upon said bearing-shaft connected to said pinionand operated thereby, and means for operating said pinion.

3. In a chalk-line case, the combination of a pair of telescopicsections, a bearing-stub formed integral with the inner face of one ofsaid sections, an auxiliary casing connected to the inner face of theopposite section, a bearing-shaft supported by said vstub in the saidauxiliary casing, a revolving pinion suitably connected to said shaftand operating Within said auxiliary casing, a sleeve or hub mounted uponsaid shaft and connected to said pinion and operated thereby, anagitatorwheel provided with a series of circumferentially-arrangedopenings connected to said sleeve and rotated therewith, a revolving concentric rack meshing with said pinion and adapted to operate the same,and means for operai-in g said rack, substantially as set forth.

In testimony whereof I alix my signature in the presence of twowitnesses.
